Description

Technical Field

[0001] This application relates to the field of road construction technology, specifically to a curbstone auxiliary installation trolley. Background Technology

[0002] Currently, with the rapid development of transportation infrastructure, road construction will inevitably become standardized, mechanized, and refined. Among these, there must be clear dividing lines between the driving lanes and sidewalks of roads at all levels and even within industrial parks. These dividing lines are usually defined by curb stones. The construction of curb stones determines the progress and quality of road construction to a certain extent. Curb stones refer to the stones set at the edge of the road surface and other structural zones, and are simply called curb stones.

[0003] An existing patent (publication number: CN220301119U) discloses a rapid paving trolley for municipal road curbs, belonging to the technical field of municipal road construction equipment. It includes a base with a push rod fixedly installed on the right side. Two drive shafts are rotatably installed inside the base, with both ends of the drive shafts extending outside the base and fixedly fitted with anti-slip wheels. An auxiliary drive mechanism is provided inside the base, and a support column is fixedly installed on the upper surface of the base. A first motor is installed; when the first motor starts, it drives a steel cable to retract and release. During retraction, the steel cable, under the weight of the curbstone, moves two sliders on the same side closer together, causing a clamp to hold the curbstone. After moving to the paving area, the steel cable is released, causing the fixed block to descend vertically downwards to pave the curbstone. This design reduces manual handling during curbstone paving, effectively alleviating the workload of workers and improving work efficiency.

[0004] After the trolley moves to the paving area, it releases a steel cable, which pulls the fixed block downwards vertically to lay the curbstone. However, during the release of the steel cable, the bottom curbstone is prone to shaking, resulting in an inaccurate landing point, requiring workers to make fine adjustments. Secondly, the trolley cannot move precisely parallel to the curbstone section during its movement, requiring workers to constantly correct the trolley's position, which affects construction efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a curbstone auxiliary installation trolley, which has advantages such as high efficiency and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a curbstone auxiliary installation trolley, including a base plate, a rotating shaft rotatably connected to the upper surface of the base plate, an installation plate fixedly connected to the top end of the rotating shaft, a base fixedly hinged to the upper surface of the installation plate, a sleeve hinged inside the base, a rod slidably inserted inside the sleeve, a connecting plate hinged to the left end of the rod, a clamping frame fixedly connected to the bottom end of the connecting plate, and a clamping plate slidably connected inside the clamping frame;

[0007] The upper surface of the base plate is in contact with a movable frame at its rear end. A limiting frame is provided below the top of the movable frame. A limiting plate is slidably connected inside the limiting frame. A set of rollers is rotatably connected inside both the limiting plate and the limiting frame.

[0008] The above-mentioned solution, through the design of the limiting frame and limiting plate, can firmly clamp the installed curbstone section, providing stable guidance for the overall installation process. This design ensures that the base plate moves parallel along the predetermined road section, effectively avoiding deviation and twisting, thereby guaranteeing the straightness and overall flatness of the paved section and significantly improving the quality standards of road construction. Secondly, the roller design greatly reduces the frictional resistance between the base plate and the curbstone, making the movement of the base plate smoother and more stable. At the same time, through the ingenious combination of sleeve, insert rod and connecting plate, stable support is achieved for the curbstone during lifting and paving, effectively avoiding the problem of unstable installation caused by curbstone shaking in traditional methods, and improving the stability and safety of installation.

[0009] Furthermore, a fixing sleeve is fixedly connected to the outer surface of the sleeve, and a first hydraulic rod is fixedly connected inside the fixing sleeve. A synchronization plate is fixedly connected to the output end of the first hydraulic rod, and the bottom end of the synchronization plate is fixedly connected to the left end of the insertion rod.

[0010] The above scheme, through the arrangement of the synchronization plate and the first hydraulic rod, enables the extension of the insertion rod.

[0011] Furthermore, an L-shaped plate is fixedly connected to the right side of the clamping frame, and a first electric telescopic rod is installed inside the L-shaped plate. The output end of the first electric telescopic rod is slidably sleeved with the clamping frame, and the output end of the first electric telescopic rod is fixedly connected to the clamping plate.

[0012] The above solution, through the installation of the first electric telescopic rod, enables the movement of the clamping plate to be powered.

[0013] Furthermore, a handle is fixedly connected to the right end of the sleeve.

[0014] The above solution, with its grip design, makes it easy for users to press down or lift the sleeve.

[0015] Furthermore, multiple casters are fixedly installed on the bottom of the base plate.

[0016] The above solution, with the addition of wheels, facilitates the overall movement of the device.

[0017] Furthermore, two support plates are fixedly connected to the rear end of the upper surface of the base plate, and a threaded rod is rotatably connected between the two support plates. The right end of the threaded rod is fixedly connected to the external motor output end, and the movable frame is threadedly connected to the threaded rod.

[0018] The above scheme, through the setting of the threaded rod, enables the movement of the mobile frame.

[0019] Furthermore, a second hydraulic rod is installed at the top of the movable frame, and the output end of the second hydraulic rod is fixedly connected to the top of the limiting frame.

[0020] The above scheme, through the setting of the second hydraulic rod, enables the limit frame to move up and down.

[0021] Furthermore, a second electric telescopic rod is fixedly installed on the left side of the limiting frame, and the output end of the second electric telescopic rod is fixedly connected to the limiting plate.

[0022] The above solution, through the installation of the second electric telescopic rod, can provide power for the movement of the limit plate.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This curbstone installation trolley, with its limit frame and limit plate design, can firmly clamp the installed curbstone section, providing stable guidance for the overall installation process. This design ensures that the base plate moves parallel to the predetermined road section, effectively avoiding deviation and twisting, thus guaranteeing the straightness and overall flatness of the paved section and significantly improving the quality standards of road construction. Secondly, the roller design greatly reduces the frictional resistance between the roller and the curbstone, making the base plate move more smoothly and stably. At the same time, the ingenious combination of sleeves, inserts, and connecting plates achieves stable support for the curbstone during lifting and paving, effectively avoiding the problem of unstable installation caused by curbstone shaking in traditional methods, and improving the stability and safety of the installation.

[0035] Please see Figure 1 , Figure 2 and Figure 3 The upper surface of the base plate 1 has a movable frame 10 in contact with the rear end. A limiting frame 11 is provided below the top of the movable frame 10. A limiting plate 12 is slidably connected inside the limiting frame 11. A set of rollers 13 are rotatably connected inside both the limiting plate 12 and the limiting frame 11. The setting of the rollers 13 can reduce the frictional resistance when in contact with the curb. Two support plates 21 are fixedly connected to the rear end of the upper surface of the base plate 1.
